Answer:

A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.

Answer: But what about beer-brewing, crop breeding, and the antibiotic penicillin? These processes and products – some of which have been around for thousands of years – are also examples of biotechnology.

Explanation:

Specifically, industrial biotechnology uses enzymes and micro-organisms to make bio-based products in sectors such as chemicals, food ingredients, detergents, paper, textiles and biofuels. ... Since that time, industrial biotechnology has produced enzymes for use in our daily lives and for the manufacturing sector.

Answer:

4.96 eV

Explanation:

Recall the Einstein photoeletric equation;

KE = E - Wo

Where;

KE = kinetic energy of the ejected photoelectron

E= energy of the incident photon

Wo = Work function

But

KE = eV= 1.6 * 10^-19 C * 7 V /1.6 * 10^-19 C = 7 eV

E = hf/e = 6.6 * 10^-34 * 2.9 ✕ 10^15 Hz/1.6 * 10^-19

E = 11.96 eV

Hence;

Wo = E - KE

Wo = 11.96 eV - 7eV

Wo = 4.96 eV

Answer:

4.096 kW

Explanation:

Applying,

P = Fvcos∅................. Equation 1

Where P = Power of the motor, F = Force exerted on the motor, v = Velocity, ∅ = angle.

From the question,

Given: F = 500 N, v = 10 m/s, ∅ = 35°

Substitute these values into equation 1

P = 500×10×cos35°

P = 4095.8 W

P = 4.096 kW

Hence the power rating of the moto in kW is 4.096 kW

Answer: Seema

Explanation:

When an object is on the floor, there is a force of friction acting on it. This force is higher if the object is heavier because the object would be pushing against the floor with more force.

To push such an object, one would have to apply enough force to break the friction holding the object to the floor and so with heavier objects, more force is needed to push the object because there is more friction acting on it.

Answer:

800N is the answer

Explanation:

hope it helps

The force between the objects is 200 N and when the distance between the objects is halved then the force between them will be equal to 800 N.

A force in physics is an input that has the power to change an object's motion. A mass-containing object's velocity can vary, or accelerate, as a result of a force. Intuitively, a push or a pull can also be used to describe forces.

Being such a vector quantity, a force does have magnitude and direction. The SI unit metric newton is used to measure it (N). The letter F stands for force.

According to Newton's second law's original formulation, an object's net force is equal to the speed that its momentum is changing over time.

As per the given information in the question,

Force, F = 200 N

F1 = G × m₁m₂/ r²

The final force F' = G × m₁m₂/ (r/2)²

= 4G × m₁m₂/ r²

= 4F

So, when the distance between objects is halved, then the force between them increases to 4 times.

So, the force will be,

4F = 4 × 200

= 800 N.

Answer:

so what do we need to do

Explanation:

Answer:

The intensity of the net electric field will:

[tex]E_{net}=E_{1}+E_{2}=2.52*10^{7}\: N/C[/tex]

Explanation:

Here we need first find the electric field due to the first charge at the midway point.

The electric field equation is given by:

[tex]|E_{1}|=k\frac{q_{1}}{d^{2}}[/tex]

Where:

So, we will have:

[tex]|E_{1}|=(9*10^{9})\frac{20*10^{-6}}{0.1^{2}}[/tex]

[tex]|E_{1}|=1.8*10^{7}\: N/C[/tex]

The direction of E1 is to the right of the midpoint.

Now, the second electric field is:

[tex]|E_{2}|=k\frac{q_{2}}{d^{2}}[/tex]

[tex]|E_{2}|=(9*10^{9})\frac{8*10^{-6}}{0.1^{2}}[/tex]

[tex]|E_{2}|=7.2*10^{6}\: N/C[/tex]

The direction of E2 is to the right of the midpoint because the second charge is negative.

Finally, the intensity of the net electric field will:

[tex]E_{net}=E_{1}+E_{2}=2.52*10^{7}\: N/C[/tex]

I hope it helps you!

The net electric field midway between these two charges is 2.52 x 10⁷ N/C.

The electric field strength between two point charges is the force per unit charge.

Electric field strength due to +20.0 μC charge

[tex]E _1 = \frac{kq_1}{r^2} \\\\E_ 1 = \frac{9 \times 10^9 \times 20 \times 10^{-6}}{(0.1)^2} \\\\E _1 = 18 \times 10^6 \ N/C[/tex]

Electric field strength due to -8μC charge

[tex]E _2 = \frac{kq_2}{r^2} \\\\E_ 2 = \frac{9 \times 10^9 \times 8 \times 10^{-6}}{(0.1)^2} \\\\E _2 = 7.2 \times 10^6 \ N/C[/tex]

The net electric field midway between these two charges is calculated as follows;

[tex]E_{net} = 18 \times 10^6 \ + \ 7.2 \times 10^6\\\\E_{net} = 25.2 \times 10^6 \ N/C\\\\E_{net} = 2.52 \times 10^7 \ N/C[/tex]

When a space ship is accelerating in space, there is a force known as Inertia that kicks in. Inertia will mirror the effects of gravity on the ship even if there is no gravitational field effect such that anything that would happen where there is gravity, would continue to happen.

This means that apples will fall from trees, people's feet will touch the ground, sky divers will be pulled downwards and balls will bend downwards when thrown as well. These are the same effects expected on earth where gravity pulls things towards the earth's core.

Answer: Diagram A

Explanation:

The Grand Canyon was created by the constant flow of the Colorado river which physically broke down the rock for billions of years. It then carried off the rock as it flowed and as it kept doing this, the canyon kept getting deeper and deeper.

This is what is described in the first diagram. The water from the faucet is carrying the soil along with it much like the Colorado did to the rocks of the Grand Canyon.

Answer:

Gravitational force between two bodies depends on:

1. Masses of the two bodies. The greater an object's mass, the greater its gravitational force.

2. Distance of separation between them. The smaller the distance greater is the gravitational force.

Answer: 2.35 m/s

Explanation:

Given

Dog completes 4 laps around the tree in  32 seconds

Radius of the circular path is 3 m

Time period for single lap is  [tex]\frac{32}{4}=8\ s[/tex]

Length of the track is equivalent to the perimeter of the path

[tex]\Rightarrow L=2\pi r\\\Rightarrow L=2\pi \times 3\\\Rightarrow L=6\pi\ m[/tex]

Tangential velocity is given by

[tex]\Rightarrow v_t=\dfrac{L}{t}\\\\\Rightarrow v_t=\dfrac{6\pi}{8}\\\\\Rightarrow v_t=2.35\ m/s[/tex]

Thus, the tangential velocity is 2.35 m/s
